Concrete Prefabricated House Model

Concrete prefabricated house models are mainly divided into two categories: mold types and prefabricated building training and teaching models. Here is a detailed introduction:

Mold Types

1. Cement House Molds: These have evolved from traditional large steel formwork for buildings and are used for factory-prefabricated integral concrete houses. The core components include mold liners, exterior wall molds, bases, and slide rails, with a self-weight exceeding 20 tons, requiring strict adherence to safety operation procedures. The molds form a casting cavity through opening and closing, combined with steam curing processes to accelerate concrete hardening. They have undergone four generations of technological upgrades: the first generation featured a simple structure, the second generation achieved vertical wall forming, the third generation supported multi-size adjustments, and the fourth generation adopted a fully automatic hydraulic system integrated with electric vibration functions. The molds can be reused for approximately 5-8 years, with wall thicknesses ranging from 14-17 cm and slab thicknesses from 10-13 cm, enabling centralized prefabrication of components to shorten construction periods and adapt to the production needs of housing factories of different scales.
2. New Modular Concrete Prefabricated House Molds: These can be easily disassembled and flexibly customized, changing the image of heavy equipment previously divided into exterior and interior liners. They can cast concrete into five-sided boxes but have the issue of high mold costs.

Prefabricated Building Training and Teaching Models

1. Structural System Models:
   • Prefabricated Concrete Shear Wall Structural System: With dimensions of 1800 mm × 1200 mm and a production scale of 1:25, it displays areas for component lifting, concrete work, mold removal, stacking, and transportation. The main components include laminated slabs, prefabricated exterior walls, prefabricated interior walls, prefabricated stairs, PFC corners, and prefabricated balconies.
   • Prefabricated Concrete Frame Structure: With dimensions of 1800 mm × 1200 mm and a production scale of 1:25, it displays areas for component lifting, work areas, steel bar processing areas, stacking areas, and transportation scenes. The main components include laminated slabs, prefabricated columns, prefabricated beams, and prefabricated stairs.
2. Production Line Models:
   • Prefabricated PC Production Lines (Sany System/Broad System): With dimensions of 2400 mm × 1200 mm and a production scale of 1:75, based on the real production lines of well-known domestic enterprises, they display typical domestic 4+1 layouts, including multifunctional production lines, fixed mold table production lines, double-skin wall production lines, steel bar processing lines, and concrete processing lines.
3. Grouting Demonstration and Operation Models:
   • Prefabricated Concrete Sleeve Grouting Demonstration: This displays grouting operation scenes, including operators, prefabricated exterior walls, concrete mixers, pressure tanks, and compactness detectors.
   • Prefabricated Concrete Sleeve Grouting Operation: With dimensions of 1200 mm × 1800 mm and a production scale of 1:6, it includes single-sleeve grouting practical operations (transparent prefabricated columns, sleeves) and combined chamber grouting practical operations (transparent prefabricated walls, sleeves), which can be cleaned and practiced repeatedly.
4. Prefabricated Component Models:
   • Large-Scale Prefabricated Components: Within dimensions of 1200 mm × 2400 mm and production scales of 1:1/1:2, some are realistic and some are sectioned to display the internal steel bars and connectors of prefabricated exterior walls, interior walls, stairs, beams, columns, double-skin walls, air conditioning panels, and balconies.
   • Small-Scale Prefabricated Components: With dimensions of approximately 300 mm × 300 mm and a production scale of 1:10, they are sectional displays of large-scale components.
5. Connection Node Models: Within dimensions of 400 mm × 350 mm and a production scale of approximately 1:6, they include dozens of prefabricated building nodes, such as construction of post-cast strip formwork for laminated slabs, sleeve grouting structures, and construction treatments between prefabricated exterior walls.
